I would not get 30# tanks. Jacko hit the nail on the head. As a matter of fact for anyone near Tallahassee I have 2 30# tanks and a back cover I will trade straight up for 20# and a black cover. Just provide them full and pay for a fill for one of my extra 20's to make the fuel even.
I have the table, and I like it. The table is generic, but they built a nice place to hold it, and I am not sure that the storage hole is prebuilt without the option. Then again my passthrough is always a disaster and any built in organization is a good thing!
Power remote is silly without power stabilizers I think, and I'm not a fan of power stabilizers.
Kitchen skylight. Provides some light, but its a hole in the roof. Personally I'd opt out.
The rear gas grill is nice, but other options exist. If I had not had gotten it with my last RV and kept it, I wouldn't have it and would be using a Webber Q of some sort.
My unit HAD the chill and N-store and it was removed the 5th day of owning the RV.]
I would go to www.rvdirect.com
and get a quote on what you want and add all options. Even if you buy local, it gives you negotiating power.
